Two maths worksheets dealing with addition and subtraction of a single digit to a 3-digit number. Unlike traditional sums different parts of the number sentence are missing.
For example: one question is 584 + ? = 593.
This can be done in several ways, counting on 6 from 584 to 590 and then another 3 to 593 probably being the most effective.
The last 5 questions on both sheets ask for a quick explanation of the method used. Make sure that this is done as it can reveal a great deal about the way your child is thinking about numbers.
